Inventor: JOHNSON JAMES YATE
Filed: 1897-01-29
Granted: 1897-12-04
Abstract: 2472. Johnson, J. Y., [Boehringer & S÷hne, C. F.]. Jan. 29. Hydroxycaffeine. - Hydroxycaffeine which is identical with 1.2.3-trimethyl-uric acid, is prepared by methylating uric acid or 1.3-dimethyl-uric acid with a methyl halogenide, methyl nitrate, or methyl hydrogen sulphate, in presence of at least one molecular proportion of caustic alkali for each non-methylated imido group, and at a low temperature, preferably in a solution cooled by ice. When the reaction is complete the mixture is slightly acidified and concentrated for separating the hydroxycaffeine in crystals. When uric acid is the starting point, any dimethyl - uric acid produced is first separated.

Title: Improvements in the Process of Making Calcium Carbide.
Inventor: BOWER GEORGE
Filed: 1898-02-28
Granted: 1899-03-28
Abstract: 4866. Bower, G., [Hewes, J. E.]. Feb. 28. Drawings to Specification. Calcium carbide.-The usual ingredients, lime (not necessarily powdered) and coke or other form of carbon, are mixed with from 5 to 10 per cent. of a flux consisting of a mixture of calcium carbonate and manganese dioxide. The whole is then subjected to an electric arc, an alternating current being employed of about 2400 ampÞres and 70 volts. One of the electrodes is gradually withdrawn until a conducting-rod has formed. The electrode is then forced inwards so as to touch the opposite electrode and a constant continuous current maintained, during which the heating action extends outwards in all directions till the whole mass is fused. Phosphorus and sulphur rise to the surface as a mixed slag of calcium phosphate and sulphide, while carbide, principally calcium carbide, but containing also some manganese carbide, forms, and is found to be quite free from phosphorus or sulphur. A special electric furnace is described suitable for this process.

Granted: 1899-02-18
Abstract: 6211. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. March 14. Acidyl-phenyl-glycine o-carboxylic acids are produced by oxidizing acetyl, benzoyl, or other acidyl deriva.tives of o-tolyl-glycine with potassium permanganate at about 80‹C. The solution is then filtered and acidefied with sulphuric acid, whereupon the product separates in colourless crystals. When treated with acids or alkalies the acidyl compounds are transformed into phenyl-glycine ocarboxylic acid. Dyes, artificial.-Indigo and derivatives thereof are produced by first preparing diacidyl indoxyl, or derivatives thereof, by acting with acetic anhydride on the salts of phenyl-glycine o-carboxylic acid, or on its mono-acidyl or other derivatives, or on the free acids mixed with sodium acetate, or the like, and then saponifying the diacidyl products with caustic soda and passing a current of air through the resulting solution. As a derivative of phenyl-glycine o-carboxylic acid, the acetyl derivative of phenyl-glycine o-p-dicarboxylic acid, which is obtained by oxidizing acetyl-m-xylylglycine, is also used. The Provisional Specification refers also to the use of the glycine compound obtained from o-amido-o-phthalic acid.

Abstract: 19,275. S÷rensen, S. C. Sept. 25. Acetylene. - Relates to generating-apparatus of the type in which water is automatically caused to pass into the carbide container or generating-vessel and be expelled therefrom in accordance with the demand upon the apparatus. To the side of a water tank a, containing an ordinary gas holder b, are attached a number of carbide containers or generating-vessels d of the form shown. Each of these is adapted to receive a carbide cartridge consisting of a perforated tin cylinder, and it is connected at its lower end to a water reservoir e inside the gas holder b, and at its upper end to a pipe g from which a bent pipe h proceeds into the gas holder. On opening the valves l and m, water rises in one of the generating-vessels d, and the gas generated passes into the holder. When the holder rises above a certain level, a regulator k automatically closes communication between the pipes g and h, and the water is forced back into the reservoir e. On the descent of the holder, the regulator k opens communication between g and h, and water again enters the generating-vessel. The height of the reservoir e is such that the lower edge of the gas holder never rises above it. As shown in Fig. 4, the generating- vessel d contains a number of conical rings w, provided with perforations x and grooves y, and adapted to receive the perforated cylindrical cartridge. It is secured in position by screw clamps v and r.
